Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to fasteners, and in particular, sub tapes and branch tapes are attached to the main tape from both ends thereof in an opposing manner to the main tape, and are alternately replaced. The present invention relates to fasteners configured to fit together.

PRIOR TECHNOLOGY Sliding fasteners, which are generally called fasteners, are made by integrating a main tape and a sub-tape, and forming a fitting part by arranging interlocking teeth on one longitudinal edge of each tape. The main tape and the sub tape are arranged in parallel with their fitting parts facing each other, and the proximal end of each tape is fixed with a fastener, and an opening/closing tool is loosely fitted into the engagement teeth at the proximal end of the tape, and the length of the tape is fixed. It is configured to open and close by sliding in the direction.

Therefore, both tapes are integrally formed in a substantially V-shape with the stopper as the base end.

There is also a fastener that can be opened and closed in a three-pronged manner, as shown in Japanese Utility Model Publication No. 37-4615.

Problems to be solved by the invention In a conventional fastener in which the sub tape is configured in a V-shape with respect to the main tape, for example, when attached to the mouth of a bag, the size of the bag can be specified, and of course, There is only one bag opening, and the size of the opening is also specified.
In addition, in the three-pronged fastener shown in Utility Model Publication No. 37-4615, a tape portion is sewn around the periphery of one large opening, and when all the fasteners are opened, the entire opening opens, If you open a section, you can open just that part, but you cannot change the size of the bag by just using one fastener.

Means for Solving the Problems The purpose of the present invention is to provide a fastener with functions and effects not found in conventional fasteners.In particular, one fastener has three tapes with fasteners attached to them for opening and closing. Equipped with two tools, the secondary tape and the branch tape can alternately engage the main tape with each end of the main tape as a starting point, and by using this, for example, the size of the bag can be changed to a larger or smaller size. Specifically, it provides a fastener that can be changed into a main tape, a sub tape, and a branch tape, each of which has a large number of fastening teeth arranged side by side on one end side edge in each longitudinal direction to form a fitting part. are formed to have approximately the same length, and are stacked in the same manner so that the leading edge of the branch tape rests on the proximal edge of the secondary tape, so that the main tape and the fitting part are parallel to each other in a facing manner, and the proximal end of the main tape is and the proximal end of the secondary tape with a fastener, and fitting the main opening/closing tool into both opposing fitting parts,
Connect the tip end of the main tape and the base end of the branch tape with a fastener, fit the secondary opening/closing tool into both opposing fitting parts, and use the main opening/closing tool to connect the main tape and the secondary tape. The fastener is characterized in that the fitting part of the main tape and the branch tape is opened and closed by a sub opening/closing tool when the sub tape is opened.

Effects According to the present invention having the above structure, the sub tape and the branch tape are connected to the base end and the distal end of the main tape in such a manner that they can be vertically overlapped, and the distal end of the sub tape and the branch tape are When pulled apart from the main tape, it can be made into a substantially U-shaped flat surface.

Therefore, the main tape and the sub-tape are arranged at the opening of the bag with the fitting parts facing each other, and the branch tapes are arranged with their distal and proximal ends at both ends of the opening. When the middle part of the tape is arranged in an arc shape at the center of the front of the bag, the bag can be used to its full size when opening and closing the main tape and the sub tape. When the main tape and the sub tape are opened and the main tape and the branch tape are opened and closed, the bag material between the branch tape and the sub tape goes into the bag, resulting in a roughly semicircular bag. It can be transformed into a small bag.

Embodiment An embodiment of the present invention will be described based on the drawings. The main tape 2, sub-tape 3, and branch tape 4 of the fastener 1 have approximately the same length, and are fitted with a large number of fastening teeth 5, 5... attached at predetermined intervals on the edge of one side in the longitudinal direction. It forms part 6.

First, the main tape 2 and the sub tape 3 are arranged in parallel with the fitting portions 6 facing each other, and the base end of the main tape 2 and the base end of the sub tape 3 are integrally connected with the fastener 7. However, a main opening/closing device 8 is fitted into the connecting teeth 5, 5, . . . at the base end portions of both tapes 2, 3.

Further, the fitting part 6 of the main tape 2 and the fitting part 6 of the branch tape 4 are made to face each other, and the branch tape 4 is
The connecting teeth 5 of both tapes 2 and 4 are arranged so as to overlap directly above the secondary tape 3, and the distal end of the main tape 2 and the proximal end of the branch tape 4 are integrally connected with a stopper 9. The sub-opening/closing tool 10 is fitted in 5....

In the fastener 1 having the above configuration, when the main opening/closing tool 8 is slid in the longitudinal direction of the fitting part 6 to open and close the fitting between the main tape 2 and the sub tape 3, the branch tape 4
When the main tape 2 and the sub tape 3 are left loose and the fitting between the main tape 2 and the sub tape 3 is released, the fitting portion between the main tape 2 and the branch tape 4 can be opened and closed by sliding the sub opening/closing tool. Reference numeral 17 in FIG. 1 is an end fitting.

Therefore, when used in a bag as shown in FIG. 2, the size of the bag can be divided into a large size and a small size.

The bag 11 shown in FIG. 2 has a flat, oval outer fabric 12.
and the same-shaped lining fabric 13 are stacked on top of each other, and the long axis both ends A
The lower edge of the straight line connecting points B and B is sewn together to form the bag bottom 14, and the other edge is not sewn to form the openings 15 and 16, creating a so-called gag-shaped opening. It's in a bag. The size of the bag 11 is arbitrary, but for example, the distance between A and B is 40 cm, and the short axis is 25 cm.
shall be. The negative cross section in FIG. 2 is shown in FIG. 3. Opening part 15,1 of this bag 11
The main tape 2 and the sub tape 3 are sewn to the edge of the tape 6. That is, the base ends of both tapes 2 and 3 are arranged at point A, the secondary tape 3 is sewn to the edge of the opening 15 of the outer fabric 12, and the main tape is sewn to the edge of the opening 16 of the lining fabric 13. When 2 is sutured, the tips of both tapes 2 and 3 will be at point B.
close to the area. Next, the tip of the branch tape 4 is sewn near the point of the outer fabric 12A, and the middle part of the branch tape 4 is arranged in an arc at the center of the front height of the bag material and sewn. FIG. 4 shows an enlarged view of the inside of circle C in FIG. 2.

Therefore, when the main opening/closing tool 8 is opened or closed, the bag will open at the bottom 1.
It can be used as a large bag with 4 as the bag bottom and mouths 15 and 16 as the bag opening, but the main tape 2
When the sub-opening/closing tool 10 is opened and closed with the sub-tape 3 open, the bag 11 becomes a small bag 11 with the branch tape 4 and the opening 16 of the lining fabric 13 as the bag opening, as shown in FIG. It can be transformed into. FIG. 6 is an enlarged view of the circle D in FIG. 5, and FIG. 7 is a cross-sectional view taken in FIG.

Note that the present invention is not limited to the above usage example, and can be used freely.

The bag 11 may be made of any material such as woven fabric, knitted fabric, net, leather, and non-woven fabric. Regarding the shape and purpose of the bag, for example, it can accommodate up to 5 to 6 basketballs, and when it is made into a small bag, it can accommodate 2 to 3 basketballs.

Also, as a laundry net, you can use different sizes of bags depending on the amount of laundry. In addition, it can be used as a pencil case, a coin purse that doubles as a key holder, a sports bag, a hand bag, a travel toiletry bag, a seal bag, etc.

The material of the coupling tooth may be made of synthetic resin, metal, etc., but it is preferable to use a material that has directional flexibility so that it can be opened and closed even if the mounting direction of the opening/closing tool is reversed. In addition, materials other than metal may be used for opening/closing fittings, fastening fittings, and end fittings, regardless of their names.
It goes without saying that the tape fastener may also have an open fastener type shape other than that shown.
The effect remains the same no matter where the sub tape or branch tape is placed, left, right, up or down.

Effects As described above, the present invention allows the secondary tape and the branch tape to be opened and closed alternately with respect to the main tape. The tape is attached to the side edges of the bag, and when the bag is used in a large size, it is used to open and close the main tape and sub tapes, and when the main tape and branch tapes are connected and opened, the large bag is transformed into a small bag. There are effects such as being able to.
